A while back, MS was offering the "Windows 8 Media Center Pack" for free. I entered my info and got an email with the product key. I followed the instructions on my desktop and all was fine. Today, I thought I'd try to install the same pack on my surface thinking that the product key might be like some other products that can be installed on a couple of computers. I figured the worse case scenario would be an activation error and I could just remove it. Wrong. When you install the Media Center Pack, it changes the entire operating system sku - which now rendered my Surface as un-activated. There also doesn't appear to be any easy way to revert. The online Surface support tech wanted me to do a restore. Screw that! The Media Center license is only $10 so I figured I'd just buy it. The problem was that I got an error saying I couldn't buy product keys online in my region (I know Idaho is a little backwoods but I didn't think we were a 3rd world country or anything). I called MS licencing support and after about 45 min. of trying to correct the purchase error, the tech, who was very polite, just gave me a new product key for free.
